Hijacking the thread back from the (interesting) Typ XXIII discussion:

I am holding the SN Typ IIA kit in my hands now. I noticed that the forward hull pieces have rests of casting channels on the separation line, so that it is not possible to hold the hull halves together without bringing out a good knife or a small saw. There are also casting residues where the deck is supposed to meet the hull - again, no test fitting without cutting.

Talking about the deck: opening the slots in the deck will be cumbersome but doable. The slots are a bit narrower than on the VIIC, so clean work will be more difficult. A metal deck would be worth its money, I hope Eduard will come to the rescue here.

The line where the hull is vertically joined seems like a natural point of separation for RC application, to insert a WTC. The deck is not separated at that line and fine details are in the way of cutting it there, but there are ways around that.

I can safely say that a PE deck for this kit will be forthcoming. (No, it's not me)

Where the hull is split fore and aft is at an interesting location. I think this will allow SN to use the same four hull sections and then add an insert for them to make a IIB or IIC. A IID could be done the same way with the addition of add-on saddle tanks.

Does not look at all to me like scratchbuilding is the only way out. They say it in rabapla's link too: nothing that cannot be fixed by boring a few holes and filling a few slots, maybe adding a few things like diesel exhausts or jumper wire blogs. Nothing that we aren't used to doing with kits of that scale anyway.
I am happy that I have it, and I look forward to some accurising, as usual. Hey, if we could not add a few things ourselves it would be boring

As far as I am concerned, the inaccuracies in that German thread are trivial. As long as the basic shape of the boat and tower are correct, I have no problem with the model. Filling and drilling a few holes and slots is easier than relocating the anchor well on the Revell VIIC (which I will not be doing on mine).
